11c. Nylon 6 and poly(ε-caprolactone) have similar polymer backbone structure with one carbonyl, 5 methylene and a heteroatom, nitrogen or oxygen, respectively. Each is able to undergo crystallization. However, their thermal transition temperature differs significantly. The glass transition temperature (Tg) for Nylon 6 is 52 °C, whereas the Tg for poly(εcaprolactone) is 112 degree lower than Nylon 6 at – 60 °C. Similarly, the melting temperature (Tm) for Nylon 6 is 223 °C, whereas the Tm for poly(εcaprolactone) is 60 °C. Briefly explain the significant differences in the thermal properties of these two polymers.
